I agree. Although J-STD-001 references magnetics and high-frequency applications in paragraphs 1.13.2.1 and 1.13.2.2, respectively, it really leaves it up to you to define your own criteria. The external connections of those devices should conform to the requirements of J-STD-001 or NASA-8739, or whichever spec your customer calls out.

Having said that, however, I think you can use J-STD-001 and/or IPC-610 to specify what your final solder joint should look like, i.e. no voids, good wetting, no cold joints. I would call it out on the drawing. Something to the effect of: "Solder joints shall exhibit good wetting as defined by J-STD-001, para XYZ" and so on. Then I'd give the assemblers and inspectors pertinent illustrations from IPC-610 and tell them to make it look like the picture. Or you could just bond the ferrite into the waveguide. This is what we do for 99.99% of our high power waveguide assemblies. Eric Kalgren Electrical Engineer The Ferrite Co.

As you know, IPC J-STD-001D has a title with "Requirements for Soldered Electrical and Electronic Assemblies" and NASA-STD-8739.1 has the title "WORKMANSHIP STANDARD FOR STAKING AND CONFORMAL COATING OF PRINTED WIRING BOARDS AND ELECTRONIC ASSEMBLIES". I need to determine if these specifications apply when soldering ferrite absorbers (mechanical piece parts) to the inside of the RF waveguides for RF tuning purposes. Thank you in advance for your time and thoughts on this matter.
